PAPER-FASTENING DEVICE.

Application filed December 3, 1917.

To all whom it may concern:

Be it known that 1, JOHN MURRAY, a-subject of the King of Great Britainand Ireland, and a resident of Edinburgh, Scotland, have inventedcertain new and useful Improvements in Paper-Fastening Devices, of whichthe following is the specification.

The invention has for its object to provide simple and effective meansfor securing together temporarily or otherwise loose sheets ofletterpress or the like by way of apertures pierced in the sheets andsuch as to maintain alinement of the sheets and also permit of thesecuring of them together or of the securing upon them of a temporarycover. The improved devices are of particular advantage as a means forthe preliminary securing of the pamphlet-s or parts in connection withthe loose-leaf binder which forms the subject-matter of my prior PatentNo. 1,243,544.

A fastening device made according to the invention comprises a tubularbody part adapted to fit within the apertures (of which there are ofcourse two or more) in the sheets, and lug parts extending preferablydiametrally and axially from the ends thereofwhich lug parts are finallyfolded over upon the sheets havingv first been pressed through thetemporary coverif there be such. The lugged tubular fastener is formedfrom a rectangular blank of thin sheet metal or other suitable materialthe width of which is substantially equal to the thickness of the blockof sheets it is desired to secure,

while its length is approximately equal.

jointly to the circui'nference and diameter of the apertures in thesheets. At one end and at opposite sides of this rectangular blank thereoutstand the lugs before referred to, which lugs are rather less inwidth than the diameter of the apertures and are of a gs. 3 and A of thedrawings Specification of Letters Patent. Patented Sept. 1'7, 1918.

ture in a series of loose leaves, and lug parts B, C extendingdiametrally and axially from its length is approximately equal jointlyto the circumference and diameter of the aperture in the sheets. At oneend and atopposite sides of this rectangular blank D there outstand thelugs B, C, hereinbefore referred to. These lugs are rather less in widththan the diameter of the aperture and are of a length adequate forconvenient folding over.

It will be seen that the improved fastener very effectively bindstogether a series of loose leaves, and it may be a cover, in suchwisethat while cover and leaves may be readily removed the whole can befreely handled without fear of their inadvertent detachment.

What I claim is 1. A fastener of the type described comprising a tubularbody having lugs projecting from the ends thereof.

2. A fastener of the type described comorising a tubular body havinglugs projecting axially from the ends thereof, and substantiallycorresponding in width to the diameter of the tubularbody.

3. A fastener of the type described comprising a tubular body. withinternal web projecting beyond the ends of the tubular body to form lugsfor the purpose specified.

4:. A blank for a fastener of the type de- 7 name to this specification,in the presence of two subscribing witnesses.
